SELF-LUBRICATING .JIIEELED VEHICLE.

Speccation of Letters Patent.

Application filed October 20. 1913. Serial No. 796.255.

following is a sjrieeitieation. 'f

This intention relates to wheeled vehicles and particularly to that class in whieh are used Heating tubular axlesl which serve as a reservoir forlulnieant.

- The invention has for its objects to provide construction of* this general"rhume.-

ter, in which each Wheel willl be secured in itsrelation tothe vehicle, independently ol inthe other wheel and of the axle; and in C which parts tixed upon the vehicle body will Y .fabut directly against the -ifnner ends of the wheelv hubs in transmit-ting thrust to the wheel flanges, and in which the body vill..

have some transverse play between the abutting ends of the Wheel hubs, though .servi Vingvto positively gage the distaneebetu'een thewlieelsavitliin necessary limits; and in which the axle will be .tree within limits to y-move lengthwise `relatively to the wheels and to the body, but will be in abutment with they body at each end of its said relative Amorement and will beveueonntered by the body before the body abuis against the wheel hub, in order that the Side thrustof the body `will develop a positive pumping action of the axle in the Wheel to force the lubricant contained Withinthe axle out into the bearing between the axle and the wheel.

The invention lWill be fully understood upon reference to the accompanying drawing, which represents the invention embodied in a known type of mine ear, and in Which- Figure 1 is a. .vertical section through a portion of the body, the` axle, the wheels and the track; Fig. '2 is a top plan view ofthe attaching box and wheel hub; Fig. 3

is a section on the line 3 3. Fig. 2; Fig. t

is a section on-the line #-4, Iiig. 2; and F ig. 5 is a Aperspective view of parts of the attaching box, hub and coupling". segregated.

1 represents the car body, 2 thi` attaching boxes, 3 the tubular axle.r and 4 the wheels.

The Wheels are constructed with flanges on the inner' ends of their hubs to receive a coupling yoke 6 to secure them to the boxes 2.` One or both of tl 'ge wheels may further prfn'ided u'ilh a illing pori T. through which to Yintroduire lubz'iraut. The outer ends el the uheel hubs; are rlosed. but are preferably formed with an enlargement S in the bore of (he wheel lo peruiil lulirirant to aeeuniulate al the end el' the axle. so that' it will be displaced inward between the wheel and the axle as the resnltoflhe pumping action of the axle incident to the tra vel of the rehirle.

i) represents pockets foi used in the al'taehin; box '2 to receive the coupling relies G.; said pockets being enlarged in the direction of end thrust upon the axle. to admit ol." szsllieient l'tst motion between the wheel and the box to inemuplish the puinpingbelion hereinafter described. The thrust is transmitted directl from the ear to the yv-heel` through the medium ot' the boxes 2. bear against the inner ends ot the-hub. The -eoupling roLes l; transmit no thrust to the wheels, but merely restrain the wheels from separation from the '.ear. -The coupling' yolies l are ot' such forni that thmr drop freely into` position in front of the flanges 5 and into the pockets El where the)Y mar be removably Seeured by means of cutter pins l0. The distance between the abuttinr faces of the attaching boxes E is such as to permit Sonie lateral movement between the body and the ivheels. so that in abutting against first one wheel and then the otherasolnemotion will be developed in the body. The axle il is restraine-'l by the boxes' onlv in transvera dirertirns: the bores through the boxes bein;r preferably enlarged. as shown in Fig'. 4. in order to avoid bindingr the axles therein against either rotaia or eudwise inoveunnt. The axles are free to anne end- \vi:-;e in the bearingr boxes 2 within limit." determined by the collars il'. which provide abutments tor the inner ends of the bern-iner boxes and eause an endu'ise pnmpius stroke to be developed in the axle br the lateral motion of the car bod)V willi/uu destrovine; the inherent eharafcter ol' ibe axle :is a lloatll'. inj axle.
